The direct measurement of the cell cycle duration in L-929 cells was performed using time-lapse photography. The cell cycle duration was 15.77 +/- 0.08 h with a standard deviation of 1.54 +/- 0.06 h. The experimental value fit to a normal distribution with a correlation coefficient 0.999. High homogeneity of this parameter and a wide range of variability of the karyotype (58-66 chromosomes) indicate that there is no correlation between these characteristics of L-929 cells. It is also shown that the difference between cell cycle durations of daughter cells tent to zero and fits by an exponent.
